Which HP OVO agent version will install in HP-UX B.10.20 server?

Hi All,

Can you assist me to install HP OVO agent in HP-UX B.10.20 server, i have tried with HP-UX11 and HP-UX11.10 version of OVO agent both . While trying to install these i am getting an error like "HP Machine Model Detection Failed".if this error is coming because of unsupported agent version, tell me the supported version of OVO agent.
